无法从"std::vector<_Ty>"转换为"std::vector<_Ty>

cannot convert from 'std::vector<_Ty>' to 'std::vector<_Ty> &

嗨,所以我有两个问题:

  1. cannot convert from 'std::vector<_Ty>' to 'std::vector<_Ty> &

    void CMapObjectPropertyPageAmbience::OnUpdateUI(CProperty* pProperty)
    {
        prt::PropertyAmbienceStringToData(pProperty, &m_propertyAmbience);
        std::vector<CFilename>& rSoundFileNameVector = m_propertyAmbience.AmbienceSoundVector;
        for (DWORD dwIndex = 0; dwIndex < rSoundFileNameVector.size(); ++dwIndex)
        {
            m_ctrlSoundFileList.InsertString(dwIndex, rSoundFileNameVector[dwIndex].c_str());
        }
        m_ctrlPlayType.SelectString(-1, m_propertyAmbience.strPlayType.c_str());
        SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_INTERVAL, m_propertyAmbience.fPlayInterval);
        SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_INTERVAL_VARIATION, m_propertyAmbience.fPlayIntervalVariation);
        SetDialogFloatText(GetSafeHwnd(), IDC_MAP_OBJECT_PROPERTY_AMBIENCE_MAX_VOLUME_AREA_PERCENTAGE, m_propertyAmbience.fMaxVolumeAreaPercentage * 100.0f);
        OnUpdatePropertyData(m_propertyAmbience.strName.c_str());
        OnChangePlayType();
    }
    

    错误出现在:

    std::vector<CFilename>& rSoundFileNameVector = m_propertyAmbience.AmbienceSoundVector;
    
  2. 2 个重载都无法转换所有参数类型:

    void CMapObjectPropertyPageAmbience::OnDeleteSoundFile()
    {
        DWORD dwCurSel = DWORD(m_ctrlSoundFileList.GetCurSel());
        if (dwCurSel >= m_propertyAmbience.AmbienceSoundVector.size())
            return;
        DeleteVectorItem < CFilename > ( & m_propertyAmbience.AmbienceSoundVector, dwCurSel);
        m_ctrlSoundFileList.DeleteString(dwCurSel);
    }
    

    DeleteVectorItem<CFilename>(&m_propertyAmbience.AmbienceSoundVector, dwCurSel);

完全错误

您正在尝试在预期vector<CFilename>的地方使用vector<string>。这些是完全不相关的类型。
